Dr. Phil Maffetone: Adjustments to the 180 Formula

Debunking myths with Dr. Phil

2 Comments

In regards to heart rat training, I have been utilizing Dr. Maffetone’s approach in my training for a short time. I recently started a very low carb diet. One thing I have noticed is that my resting heart rate has gone up. Also, I can’t cover as much distance while keeping my heart rate in the MAF zone. I have only been on the diet for about 2 1/2 weeks. I thought I was getting enough salt but perhaps I have not.
I really wanted to give the low carb and MAF training a serious effort. Is this something I should expect to change over time?

So true….I stopped running for awhile (many months) then tried to run my ‘normal’ pace and struggled. I strapped on my heart-rate monitor, slowed the pace down as Dr Maffetone suggested, and a month later my pace improved. It felt so awkward to run more slowly, but it worked and helped me train in the zone more comfortable.
